Definitions

  • This invention relates generally to dental hygiene devices and more specifically concerns a power- driven acoustic toothbrush having a selected range of bristle tip velocities so as to produce high performance results.
  • Conventional toothbrushes attempt to produce the desired cleansing effect by scrubbing the surfaces of the teeth to remove dental plaque. Flossing is typically recommended in addition to brushing to reach those tooth areas which cannot be reached by a brush.
  • a first category or group of devices involves the water jet phenomenon.
  • Representative examples of patents in this group include U.S. Patent No. 3,227,158, to Moret, and U.S. Patent No. 3,522,801 to Robinson.
  • these devices use a pulsating, highly directed stream of fluid to remove material from around the teeth.
  • these devices do have significant disadvantages, including a requirement of relatively high water pressure.
  • these devices are not very effective in removing plaque.
  • bacteremia sometimes results from use of these devices.
  • a water jet device is powered by line voltage (not batteries) , and typically requires a significant amount of shelf space.
  • a second group of devices includes those in which a brush is vibrated at an ultrasonic frequency rate to produce a cavitation effect which in turn results in the desired cleansing.
  • U.S. Patent No. 3,335,443 to Parisi and U.S. Patent No. 3,809,977 to Balamuth are examples of such devices.
  • the primary difficulty with such devices is the requirement of providing energy through the bristles at ultrasonic frequencies, which are substantially higher than the resonant frequency of the bristles, resulting in very low efficiency of energy transfer to the tips of the applicator.
  • Safety problems may also be significant with such devices, due to the application of ultrasonic energy to tissue.
  • the invention is a dental hygiene device for cleaning teeth and interdental and gingival areas, including: a body member which includes an arm mounted for movement, typically some form of oscillating movement; a set of bristles which are located in the vicinity of one end of the arm; and means in the body member for moving the arm and hence the bristles such that the tips of the bristles move at a velocity greater than 1.5 meters per second, sufficient to produce a cleansing action with a dentrifrice fluid beyond the tips of the bristles.
  • the invention includes a method using such a toothbrush in which dental fluid is provided in the vicinity of the teeth and interdental and gingival areas to be cleaned; and the arm and hence the bristles are moved such that the tips of the bristles move through the fluid at a velocity greater than 1.5 meters per second.
  • Figure 1 is a side elevational view of the toothbrush of the present invention, showing the basic elements of the toothbrush.
  • Figure 2 is a top plan view of the toothbrush of Figure 1.
  • Figure 3 is a top plan view showing the bristles of the toothbrush of the present invention in position relative to two adjacent teeth.
  • Figure 4 is a side elevational view showing the action of the bristles of the toothbrush of the present invention relative to dental fluid and the teeth being cleaned.
  • Figure 5 is a schematic view showing the effect of bristle action of the present invention on teeth bacteria.
  • Figure 6 is a diagram showing the relationship of shear stress on bacteria pesent on teeth and the rate of dislodgement of the bacteria from the teeth.
  • Figure 7 is a top plan view showing the effect of bristle action of the toothbrush device of the present invention using a dental fluid.
  • Figure 8 is a diagram showing critical parameters of frequency and amplitude for the toothbrush of the present invention.
  • Figure 9 is an isometric view of a toothbrush of the present invention having a rotational brush action.
  • Figures 1 and 2 show the toothbrush of the present invention, generally at 10.
  • the operational effect of the toothbrush is that, by using selected bristle frequency and amplitude ranges, a significant cleansing effect is produced beyond the tips of the bristles, reaching into interdental and subgingival regions, through a layer of dental fluid, to bacterial plaque on the teeth.
  • This effect is in addition to the conventional scrubbing effect produced by the motion of the bristles when they are in actual physical contact with the teeth to be cleaned.
  • the toothbrush 10 includes a body 12 which in turn includes a handle portion 14.
  • An electromagnet 16 which comprises a stack of E-shaped laminations 18 with a coil 20 positioned around the middle leg 22 of the stack of laminations, is mounted within handle 14.
  • Coil 20 is driven by a conventional square wave oscillator, shown generally at 24, which is mounted on a printed circuit board 26 and driven by two AA size batteries 28 in the particular embodiment shown. It should be understood, however, that other driving circuitry could be used.
  • the free end tips 30-30 of the stack of laminations 18 are positioned 1-2 mm away from one end 31 of a resonator arm 32.
  • a pair of permanent magnets 34-35 are mounted on a back iron member 36 which is attached to the one end 31 of resonator arm 32.
  • the permanent magnets are made from neodymium iron boron and are mounted in opposite polarities on the flat back iron member 36.
  • Member 36 in operation, closes the magnetic flux path between electromagnet 16 and the two permanent magnets 34 and 35.
  • Resonator arm 32 is an elongated steel member, mounted by means of a steel torsion pin 38 to body 12 of the toothbrush.
  • Resonator arm 32 is fixedly secured to torsion pin 38, the ends of which are affixed to a circular collar 40 attached to the body 12.
  • the diameter and length of the torsion pin 38 are selected to provide a spring constant which resonates with the mass and compliance distribution of the remainder of the resonator arm.
  • the resonant frequency of the torsion pin is close to the drive frequency of the apparatus, e.g. 250 Hz.
  • arm 32 twists the torsion pin 38, with the torsion pin tending to maintain the resonator arm in a center position.
  • a brush head 46 At the other end 44 of resonator arm 32 is a brush head 46.
  • the bristles 47 on the brush head 46 in the embodiment shown are made of and are approximately 0.15-0.2 mm in diameter, and the tips are formed into a scalloped pattern, as shown most clearly in Figure 1, such that the bristle tips fit into the interdental crevices between teeth. There is typically a distance of 5-8 mm between successive peaks of the scalloped tips and a distance of approximately 1.5-3 mm between the tallest and shortest bristles.
  • the brush of Figures 1 and 2 oscillates in an approximate sinusoidal pattern, linearly back and forth about pin 38, within particular frequency and amplitude ranges.
  • the bristle velocity U(t) has a peak value of X Q 2 ⁇ f.
  • Operating parameters include combinations of amplitudes of up to ⁇ 6 mm and frequencies up to 500 Hz, the product of which exceeds a critical value. At typical values of amplitude (2.5 mm) and frequency (250 Hz) , the instantaneous velocity of the bristle tips is 3.9 m/s.
  • Figure 9 shows a toothbrush similar in effect to that of Figures 1 and 2, except that shaft 93 rotates, by action of motor 94, which is mounted in a body 95.
  • Motor 94 rotates shaft 93 about its major axis 96 through an angle ⁇ ⁇ (rad.) . If the bristle tips are driven at frequencies well below their resonant frequency, the tips move through an arc length of ⁇ ⁇ Rb, where Rb is the distance from the free end of the bristles to the axis of rotation 96. When the tips of the bristles are driven at a frequency near the resonant frequency of the bristles, the tips of the bristles move through a larger arc than that provided by the above formula.
  • the movement of the bristles is generally referred to herein as oscillating movement.
  • the toothbrush is held so that the brush head 46 is approximately horizontal, with the tips 49 of the bristles 47 positioned against the side surfaces of the teeth 50, typically near the gum line.
  • the bristles 47 fit around adjacent teeth, into the front portions of the interdental regions between teeth 50.
  • the motion of the brush is up and down, i.e. linearly into and out of Figure 3, toward and away from the gu line.
  • Figure 4 shows the action of bristles 52 of a toothbrush of the present invention in relation to a representative tooth 53, a gum region 54, and a mass of dental fluid 56.
  • pressure in the fluid 56 surrounding the teeth builds up, especially in the area where the gum region 54 meets the teeth.
  • the pressure will reverse, resulting in an alternating pressure field, as the brush sweeps first in one direction and then the opposite direction.
  • the pressure is concentrated on periodontal pocket 60 between the gum region and the tooth, where bacteria are concentrated.
  • the sweeping, back and forth motion of the bristles, towards and away from the gum line, causes the fluid 56 to flow at velocities which are near that of the brush, and maximizes the pressure in the interdental and subgingival regions, beyond the actual reach of the bristles.
  • the dental fluid 56 may be saliva, with additional water or a conventional dentifrice, i.e. toothpaste, or special bacteria-fighting solutions.
  • the first significant acoustic effect involving fluid-coupled effects from the movement of the bristles, concerns acoustical pressure on the plaque. Damage to the plaque results from the alternating pressure field in the dental fluid produced by the bristle movement, which is transmitted to the plaque. The plaque is believed to absorb the vibrational energy produced by the bristles, with resulting damage thereto. Further, the vibrational stress in the plaque allows entry of chemically active agents which may be present in the dental fluid into the interior of the plaque, which enhances the effectiveness of such agents.
  • the movement of the bristles creates an alternating pressure field about the teeth while maintaining a bolus of fluid near the bristle tips.
  • the pressure field created in the fluid by the action of the bristles extends into those regions which are not reached by the bristles themselves.
  • the pressure on the fluid which is forced to flow at the bristle tip velocity, is approximately 9 kPa.
  • the pressure falls off with the cosine of the angle of the direction of bristle movement.
  • the pressure will be focused in line with the bristles, primarily toward the periodontal regions and the interdental gap.
  • the best results are achieved when the brush is positioned such that the bristles sweep into and over the gumline, forcing the fluid to move back and forth over that region ahead of the tips of the bristles.
  • the pressure created by the alternating action of the bristles in the fluid is also transmitted through the tissue area, which is typically 0.5-2.0 mm thick.
  • the pressure field thus actually reaches and disrupts the bacteria within the periodontal pocket to a substantial (up to 50%) extent.
  • the actual pressure produced by the oscillating (reciprocating) bristles can be approximated by the well-known formula for pressure produced by an oscillating sphere.
  • a second acoustical effect is the shear stress effect on the bacteria caused by movement of the fluid.
  • oral plaque forming bacteria shown generally at 66, will typically have attachment organelles, referred to as fimbrii or pili, which attach the bacteria to the surface 70 of teeth, as well as to each other.
  • fimbrii or pili attachment organelles
  • Such bacteria are dislodged from teeth surfaces if the shear stress on the bacteria exceeds a critical value.
  • the critical shear stress for various bacteria will vary according to species.
  • Figure 6 shows the relationship between shear stress ( ⁇ ) and the rate of bacterial dislodgement. It has been discovered that when the shear stress exceeds the critical value, a rapid increase in dislodgement occurs.
  • Typical oral bacteria which are attached to dental surfaces have critical shear stresses in the range of 30-300 Pa.
  • the force to produce the required shear stress is provided by the dental fluid flowing back and forth over the tooth.
  • the action of the bristles forces the fluid to flow at a particular velocity (the velocity of the tips of the bristles) across the surface of the teeth, including along the interdental channel between adjacent teeth, where a bolus of fluid is forced to flow.
  • the initial shear stress is quite high, limited by surface imperfections, e.g. 1000 Pa.
  • a boundary layer builds up with a resulting decrease in shear force, with values proportional to bristle tip velocity.
  • Shear stress on the plaque increases significantly when abrasive particles are present in the dental fluid near the surface of the teeth.
  • a particle in the dental fluid which is moving at 2 m/s at a distance of 10 micrometers from the plaque will result in a shear stress of approximately 10,000 Pa on the plaque, even though the particle itself does not actually contact the plaque.
  • critical levels of shear stress can be produced on the plaque at distances 2-3 mm from the tips of the bristles with the present invention.
  • the oscillatory nature of the shear force produced by the vibrating bristles provides added effects in the dislodging or dispersing of attached bacteria. Because the fluid velocity alternates in direction, fatigue is produced in the bacterial attachments. Fatigue fracture of a bacterial bond occurs in proportion to both the level of applied shear force and the number of times the direction of the shear force reverses. Since teeth are brushed only for a relatively short time (the maximum for the entire mouth area is probably about 3 minutes) , the higher the frequency of oscillation, the greater the number of times the bacteria will be subjected to the reversing of the direction of the shear force. Accordingly, if the shear force remains the same, a higher frequency will produce fatigue fracture more quickly.
  • a third acoustical effect of the present invention occurring beyond the tips of the bristles is the abrasive erosion (Figure 7) created by movement of the bristles 70 in a dental fluid 72 which also contains abrasive particles 74.
  • the fluid 72 flows back and forth by virtue of the action of the bristle tips, which are typically in relatively light actual contact with plaque layer 77.
  • the fluid moves back and forth with the bristles, as indicated by the solid lines 78 and dotted lines 80.
  • the damage which is caused to plaque 77 increases rapidly with the tip velocity of the bristles, since the rate of impact as well as the momentum of the particles in the dental fluid increases with velocity. It has been discovered that below a particular threshold value of bristle velocity, the impact of the particles results in only an elastic stress on the plaque formation, as opposed to actual damage. Thus, significant erosion, like the other acoustic effects, is dependent upon critical velocity levels.
  • the bristle movement in a fluid with abrasive particles produces a turbulence in the direction of the flow of the fluid.
  • This turbulent flow is characterized by velocity components in all directions within the fluid, such that the plaque layer is hit by abrasive particles from a variety of angles, rather than strictly along the dental surface as would be the case with laminar flow only.
  • a fourth significant acoustic effect is produced by the present invention when the bristles rapidly move back and forth, resulting in quantities of air being pulled into the fluid, in a supersaturation effect.
  • This supersaturation effect results in oxygen being present in the fluid around the tips of the bristles significantly above the normal oxygen tension level.
  • This supersaturated fluid then moves into the subgingival regions, for instance, replacing fluid there which may contain very little oxygen.
  • Anaerobic bacteria thrive in those areas, such as the periodontal regions, where there is little or no oxygen present. Significant damage is done to all classes of anaerobic bacteria by the movement of oxygen-containing fluid into those regions.
  • the supersaturation of dental fluid in effect provides a reservoir of oxygen for the periodontal tissues above the normal oxygen tension level, resulting in a longer-term effect on the anaerobic bacteria.
  • the more rapidly the bristles vibrate and the greater the amplitude of vibration the more significant is the capturing of oxygen within the fluid and the greater the effect on the anaerobic bacteria.
  • a vortex action results which pulls air into the fluid, and when the bristles reverse direction, the air is entrained in the fluid. The more rapid the movement, the greater the vortex action. Bubbles of oxygen typically are propelled into crevices and pockets of the teeth, as well as the gingival areas.
  • the oxygen bubbles are propelled with such initial velocity that they propagate 2-3 cm outwardly from the tips of the bristles if unimpeded, so they easily reach periodontal pockets remote from the bristle tips.
  • the dentifrice itself may contain small bubbles of oxygen and/or oxygen-containing agents such as hydrogen peroxide, which results in an increased effect compared to air as the oxygen source by raising the oxygen tension level above that of atmospheric.
  • certain active ingredients such as sanguarine, alcohol, various fluorides and chlorhexidine can be used in the dentifrice, and are diffused and/or driven into the crevices of the teeth and the periodontal gingival regions. This can aid in preventing tooth decay.
  • the acoustic effects normally produced by the toothbrush of the present invention as described above will disrupt the plaque matrix, allowing effective penetration of the oxygen and/or the dentifrice agent into the bacterial structure.
  • Figure 8 shows the critical operating regions.
  • One axis shows the amplitude of movement of the bristles, while the other axis shows the frequency of the movement of the tips of the bristles.
  • the velocity of the bristles must be greater than a critical threshold value "U ⁇ j ⁇ " in meters/second, in the range of 1.5 - 2.0 meters/second, for the fluid coupled therapeutic effect to be significant.
  • u crit ⁇ n turn ⁇ s determined by frequency and amplitude.
  • the diagonal line 98 in Figure 8 corresponds to a U cr i-
  • the vertical edge 100 of triangular region 99 corresponds to amplitudes of ⁇ 6 mm, beyond which increases in amplitude becomes impractical, because of limited room in the oral cavity.
  • the horizontal edge 102 of region 99 corresponds to frequencies of 500 Hz, above which increases in frequency are irritating to human hearing and are above the resonant frequency of the bristles.
  • An appropriate frequency range is 40 Hz - 500 Hz and an appropriate amplitude range is 0.5 mm - 6mm.
  • the critical region 99 is remote from the operating characteristics of other known power toothbrushes and when the toothbrush of the present invention is operated within this region, significant cleansing effects are achieved beyond the bristle tips.
  • the present invention also produces acoustic pressure levels far above other commercial power toothbrushes. Typically, a threshold acoustic pressure level is 1.5 kPa.
  • the tooth brush will be constructed so that the operating frequency of the bristles is below their resonant frequency, but close enough thereto to permit a bristle amplitude greater than the amplitude of the plate on which the bristles are mounted. Bristle movement is also typically 2-3 times that of the resonance arm. This facilitates driving the bristle tips to the desired velocity without having to drive the coupling elements, such as the resonance arm, the full amplitude of the bristle tips.

Abstract

L'appareil d'hygiène dentaire comprend un corps principal (12), d'une extrémité duquel s'étend un bras résonateur (32). Le bras (32) qui produit une oscillation sur une tige de torsion (38) est monté au moyen d'un électro-aimant (16) dans le corps principal, et fonctionne en combinaison avec deux aimants permanents (34, 35) qui sont montés à l'extrémité arrière (31) du bras résonateur (32). Un ensemble de poils (41) est monté à l'extrémité avant du bras résonateur (32). Le bras (32) est mû de façon que les extrémités des poils vibrent dans certaines plages d'amplitude et de fréquence, pour que la vitesse de déplacement des extrémités des poils soit supérieure à 1,5 m par seconde, ce qui permet d'assurer un nettoyage très performant des surfaces en contact avec elles.
